State capital Mainz calls for participation in Earth Hour

The state capital of Mainz is once again taking part in this year's "Earth Hour", following the call of the environmental foundation WWF Germany to set a visible example for climate protection and social cohesion.

Through “Earth Hour,” people, cities, and companies are committed to protecting the foundations of our lives and will turn off their lights for one hour worldwide on Saturday, March 28, at 8:30 p.m., under the motto “We’re turning it off.” Famous landmarks will once again be plunged into symbolic darkness, including icons such as the Brandenburg Gate in Berlin and Mainz Cathedral. 

Janina Steinkrüger, Head of the Environmental Department: “Earth Hour reminds us of how much we can do together for our planet. I warmly invite all residents of Mainz to join in and turn off their lights for this hour to send a visible message in support of climate and environmental protection.”
